Stop in for a cup of coffee

Do you know if anyone drilled a set of drums to help dissipate the off gassing? Seems like it would work....
Fred Puhn writes about doing that for racing in his Brake Handbook.
Be interesting to find out if that was done by Petty or earlier stock car racers before disks became available.
Now a days about the only folks racing with drums on the front have cars like the Corvair in vintage racing, or long lived SCCA classes like Formula V. Those are probably the folks who would know the most about pushing drums to the limits.
